I have noticed that when I am in race mode, or when i change from D mode to S mode, the car sounds louder and whilst driving it tends to take much longer to change gears. when I was going 80km, I was still stuck on S3 or S4.

1. is this normal?

2. I use comfort mode for daily driving in the city, but i was wondering what the use of the S mode or race mode was used for?

3. Also does it use more petrol when you are using the S mode?

4. Is it a bad idea to keep the mode in race mode always? is it bad for the engine?
